Paris: Tunisian-born designer Azzedine Alaïa, a fashion iconoclast whose clingy styles helped define the 1980s and who dressed famous women from Hollywood to the White House, has died. The French Haute Couture Federation announced Alaïa's death on 18 November without providing details. Twitter tributes to his influence on fashion poured in from around the world.

Alaïa ((AZ'-uh-deen uh-LY'-uh) sometimes was dubbed the "king of cling" for the sculptural, formfitting designs he first popularized during the 1980s and updated over the decades. His clients included women as diverse as Michelle Obama, Lady Gaga, Grace Jones and Greta Garbo.

Secretive and known as a fashion rebel, Alaïa was based in Paris for decades but did not take part in the French capital's seasonal fashion frenzy or flashy ad campaigns. Instead, he showed privately on his own schedule.

The couture federation said Alaïa was born in 1940, while the Tunisian Culture Ministry said he was born in 1942. The discrepancy could not immediately be explained.

The supermodel Naomi Campbell, who enjoyed a close relationship with Alaïa for many years and affectionately called him "papa," has credited the designer with helping launch her career and taking care of her like a father when she met him in Paris at age 16. In July, Campbell made a rare catwalk appearance for the designer's Paris couture show — his first since 2011 — and said on Instagram at the time: "It's always an honor to walk for you 1986-2017."

News of his death sparked a flurry of tributes from figures in the fashion and entertainment worlds.

Ralph Toledano, head of the French Haute Couture Federation, told the AP that Alaïa was "an exceptional friend and marvelous person."

"An architect for the body, a man for femininity, Azzedine Alaïa is undeniably the inventor" of an important kind of style, Toledano said. Fashion designer and former Spice Girl Victoria Beckham said on Twitter that it was a sad day and called Alaia "true master and one of my biggest inspirations." Singer Rihanna posted an online photo showing a fond moment between her and the famed designer, saying "you will live on forever." Indian actress Sonam Kapoor said she was "deeply saddened" by the news and thanked Alaïa for "always empowering women and embracing diversity."

As a rare Tunisian with global name recognition, Alaïa's death prompted collective grief in his native Tunisia on Saturday, with tributes pouring in from the business and culture worlds and the government. The Tunisian Foreign Ministry said in a statement that Alaïa was born in the medina, or old town, of the capital Tunis in 1942, and developed a passion for fashion thanks to his sister Hafidha. It said he had expressed a wish to be buried in Tunisia.

His house's website described him as "the little man in eternal Chinese pajamas" who "built a legend, that of a rebel designer who worked against the system and its trends." Multiple museums have held retrospectives of Alaïa's work, including the Guggenheim in New York and Paris' Palais Galliera, which put on a show in 2013 that highlighted his way of "slowing down time."

"A genius who weaved connections among fashion, architecture and fine arts, sculpting creations to magnify women's bodies. A free and generous man, loved and admired," former French Culture Minister Audrey Azoulay, who recently became director of the United Nations cultural agency UNESCO, said in tribute to the designer.

His star status was memorialized in the 1995 comedy Clueless when the lead character objects to a robber's demand to get on the ground, saying her red dress is "An Alaïa. It's like a totally important designer."

Azzedine Alaïa was raised by his grandmother and earned a diploma at the Tunis Fine Arts Institute, according to his house's website. He arrived in Paris in the 1950s, where he rented a room in a countess' home in exchange for small jobs.

He learned to sew at Guy Laroche and worked briefly at Christian Dior, and started his own house in 1980. He worked with superstars as well as low-cost retailer Tati, well before H&M popularized that kind of high-low cooperation with well-known designers. Alaïa received offers to take over other fashion houses, but he routinely refused. He sought financial support in the 1990s and kept his company going. It had a revenue of 60 million euros last year.
